I am rather in the mood for a road trip. Planning one used to be pretty much hit or miss. Now however, nobody needs those special fold-out maps that the AAA used to provide. I can easily check driving time by just putting "distance place 1 to place 2" into Google. That's good for figuring out how much mileage per day makes sense. Then, one can pop into Google Maps to get a better idea. As well, I drop into Street View to get a view of the terrain. For example, here's eastern Washington State near where I-90 crosses the Columbia River.
It might be fun to take several nights to skirt across the southern BC and cross the border so as to visit Coeur d'Aline, Idaho. Then, we'd be able to take I-90 West and stop in at Lynne and Joel's for the night. The fifth day could be a 200 mile half day coming back to BC from their house. That'd make a trip of a nearly a thousand miles in total.
